+/**
+ * @fileOverview
+ * This is an implementation of typed objects similar to the ECMAScript Harmony
+ * proposal (http://wiki.ecmascript.org/doku.php?id=harmony:typed_objects).
+ * The main difference is that it allows creating actual objects rather than
+ * merely structured data.
+ *
+ * Defining a type
+ * ---------------
+ *
+ *    const Point2D = new ObjectType({
+ *                      x: uint32,
+ *                      y: uint32,
+ *                      rotate: function() { ... }
+ *                    }, {
+ *                      constructor: function(x, y) { ... },
+ *                      bufferSize: 16
+ *                    });
+ *
+ * The first parameter to ObjectType defines object properties and methods. A
+ * name can either be associted with a type (property) or function (method).
+ * Numeric value types from the ECMAScript Harmony proposal are predefined as
+ * well as "boolean" which is an alias for uint8. In addition to that, already
+ * defined object types can be used.
+ *
+ * The optional second parameter sets type metadata:
+ *
+ *    constructor: function that will be called whenever an object of the type
+ *        is created.
+ *    bufferSize: number of objects that should be placed into a single typed
+ *        buffer (by default 128).
+ *
+ * Creating an object instance
+ * ---------------------------
+ *
+ *    var point = Point2D(5, 10);
+ *    point.rotate(10);
+ *    Console.log(point.x + ", " + point.y);
+ *
+ * The parameters 5 and 10 will be passed to the constructor function defined
+ * for this type.
